Proportional relationships (Review)
Two variables are proportional if a change in one is always accompanied by a change in the other.
The constant of proportionality and unit rate are the same thing.
If y is directly proportional to x, then the graph of y as a function of x will be a straight line. The constant of proportionality is the slope.

Hands-on, online curriculum aligned math worksheets that automatically tracks student progress.
EQ10 Constant of proportionality from the equations
EQ11 Find the constant of proportionality for each graph
EQ12 Constant of proportionality for each table
EQ13 Fill in the tables based on their constant of proportionality
Differentiation:
Accommodations for instruction will be provided as stated on each student’s (IEP) Individual Education Plan for special education, 504, at risk, and ESL/Bilingual. Differentiation will be through small groups, visuals, use of calculators, extra time, supplemental aids and reteach if necessary.
